To all whom it nuty concern.-

Be it known that I, FRANK BARCLAY, a citi zen of the United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented certain new and useful Improvements in Antifriction-Olips for Reapers or Mowers, of which the following is a specification.

My present invention relates to antifriction-clips for reapers and mowers, it being an improvement on the clip for which Patent No. 572,402 was issued to me December 1, 1896; and the invention consists, primarily, in the insertion of a steel plate between the balls and the rear edge of the sickle and in so constructing the clip as to hold this plate in place and permit a free movement of the same with the sickle, and also in making the finger of the clip separate and detachable to enable the balls to be removed and replaced without detaching the clip, all as hereinafter set forth.

Figure 1 is a top plan view, and Fig. 2 is a transverse vertical section on the line to w of Fig. 1. Fig. 3 is a perspective View of the clip with the finger detached, and Fig. 4 is a similar view of the finger shown detached. Fig. 5 is a perspective view of the clip, looking from below, showing the balls and plate in position, with plate also shown detached.

Fig. 6 is a bottom plan View of the clip with the balls, plate, and finger in position. Fig. 7 is a top plan view of a modification of the clip shown on a reduced scale.

In practice I have found that in applying my clip as formerly constructed to reapers and mowers certain difficulties were encountered which the present improvements are designed to remedy. that where the machine has been used for a considerable time the rear edge of the sickle is worn so as to form an edge more or less beveled, as indicated by the dotted lines in Fig. 2, which wedges in under or over the balls, thereby producing more or less friction also, that particles of straw, grass, or dirtoccasionally get into the pocket or recess which contains the balls and tend to interfere with their free movement, and that it was difficut to remove the same, and, further, that the balls could not be removed and replaced when broken or when for any reason it was desir- It frequently happens able so to do without removing the clip, all of which difficulties my present invention remedies.

I construct and apply the clip B to the cutter-bar A on the same general plan shown and described in my former patent. The body B of the clip is, however, made longer in order to hold the plate and afford room for its movement to and fro with the sickle-bar, as hereinafter described.

The projecting finger a of the clip may be I made integral with the body, as in my former patent, but I prefer to make it in a separate piece, as shown in Figs. 1, 3, 4, and 7, the body of the clip being made with a suitable recess to receive and hold the finger a, which when inserted therein is firmly secured in place by the bolt 1.

In Fig. 1 I haveshown the clip with three bolt-holes or slots 92, arranged to adapt it to be held by three of the bolts which fasten the finger-guards b to the cutter-bar A, in which case the finger a is brought opposite one of the finger-guards, as there shown.

In some cases it is desirable to so locate the clip as to bring the finger a midway between the finger-guards, as shown in Fig. 7, and to do that I make the body B with but two slots 01, they being so located as to adapt them to the bolts I of two adjoining finger-guards, as shown in Fig. 7. In that case the bolt 1, which holds the finger a, only extends through the body of the clip and not through the cutter-bar, there being a recess for the head of this bolt in the under side of the clip, so as to permit the clip to fit down flat upon the cutter-bar.

Either form of clip may be used and applied with equal facility to machines already in use. By arranging the finger a midway between the finger-guards, as shown in Fig. 7, the liability of grass or weeds wedging or being caught between the finger a and the finger-guard b is lessened.

At its center the body B is provided with a pocket or recess 0, as shown in Figs. 2, 3, 5, and 6, for the reception of the balls 6, the rear wall of this recess being slightly undercut or inclined, as shown in Fig. 2, to prevent the balls from working out when the finger a is removed for any purpose. To enable the balls to be removed or replaced when desired,

. I I form a slight groove 15, as shown in Fig. 3,, in the en t." art of the r Well e the eeeke l 0, so that when the finger a is removed the balls can be lifted out or dropped in at that point. I also provide a narrow steel plate It (shown detached in Fig. 5) to be inserted between the rear edge oi the sickle Q and the balls, as shown in Fig. 2, the object being to prevent the rear edge of sickles which have been worn thin by use from wedgin g in above or below the balls. This plate his made long enough t a l m s e e e the fron of e recess or pocket which contains the balls; even When .moved to and fro. by the. move, ments of the sickle, the friction between the sic l an he. met e s eheh h r at r. than th t tetien b tw en th Plat eh h balls to cause the plate to move with the. s k e.- hy th s eererihs th peehet' h p eteale ser s. to, r r rehtfne t le f st a ree dirt, sh -3 fr h e ter ng he peek t and ih rf hs'w h the tef theh ht e the bal et e eer t pretide m et ehheldih his plate in pee i h ehdn ereht h it ime being displaced or working out, I" a tee ie in th der sent. pertieh hi t heir, a ehelwh n, Fige- 2,. 5,. and 6,. th s eteeve ste pi g just she t. f he ehd eit he ma 1 the 'ehy' e'vi s t e ends t the eere leeee, h shetrhi h' is 5 e d hereby t e plate, s p evented t em Werhihs eh ehtl': i e; This sl ev h hew- F eeheed 6, is made enough longer than the ate h to permit. the le -ten te there fteelr the fre 1 therein i it earr ed h the ei hle.

It will of course be understood that so far as the use ofthe plate 77, is concerned the clip may have the finger a formed integral with its body and operate the same; but I prefer to make the finger separate or detachable, as by so doing access is given to the pocket and the balls without removing or loosening the clip.

The importance of being able to accomplish these results without moving or loosening any ofthe clips will be apparent when it is understood that there must necessarily be quite a number of them placed at intervals the whole length of the cutter-bar, and that in order to give, a proper and uniform bearing on the balls they must all be adjusted so as to make a perfect alinement of the balls, W h qu r s t me n ar With he pr nt ehet h iehi when eh th el e e ffected t e el rel h ed n the e eh 1 or the e at a Havin thee deserihed my inv n Wh clai e-- 1.
